AT97SC3204-X2M6-00

Overview

The AT97SC3204-X2M6-00 is a Trusted Platform Module (TPM) compliant with TCG TPM version 1.2 and TCG PC Client-specific TPM Interface Specification (TIS) version 1.2. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA key storage. The device communicates via a 33MHz Low Pin Count (LPC) bus and includes a FIPS 140-2 compliant Random Number Generator. It supports SIRQ and CLKRUN for power management in mobile systems.

Feature Summary

• Fully compliant with TCG TPM v1.2 and TCG PC Client-specific TIS v1.2 specifications
• Hardware crypto engine capable of computing a 2048-bit RSA signature in 200ms and a 1024-bit RSA signature in 40ms
• SHA-1 accelerator performance of 20μs per 64-byte block
• Internal NV storage space for 1756 bytes of user-defined data

Applications

• Personal computers requiring hardware-based security modules
• Embedded systems needing trusted platform capabilities
• Mobile computers utilizing LPC interface clock stopping features

Procurement Notes

Verify the specific package configuration required for the -X2M6 suffix against official Microchip documentation, as the summary datasheet lists standard packages like 28-pin thin TSSOP and 40-pad QFN. Confirm temperature range availability (commercial or industrial) and ensure compliance with current supply chain requirements before finalizing procurement plans.

Selection Notes

Select this component when a turnkey solution for TCG TPM v1.2 implementation is required. Ensure the design accommodates the 3.3V supply voltage and utilizes the 33MHz LPC interface. Consider the available package options, such as the 28-lead thin TSSOP or 40-pad QFN, based on board space constraints and thermal requirements.

Part Context

The AT97SC3204 series represents a fully integrated security module designed by Atmel (now Microchip Technology). It serves as a single-chip solution for OEMs and ODMs, providing necessary firmware and driver support for integration into various operating systems and BIOS environments. The device is part of the broader portfolio of security ICs aimed at enhancing system integrity.

Replacement Considerations

Consult Microchip's official obsolescence notices and cross-reference tools to identify any updated revisions or alternative components within the AT97SC3204 family. Verify pin compatibility and software driver updates if substituting with other TPM variants.
